Study on the ultimate shear performance of concret-filled steel tubular composite columns

Popis výsledku v původním jazyce

The shear performance of three concrete-filled steel tubular (CFST) composite columns was investigated via single-point shear tests, considering shear-span ratios of 0.75, 1, and 1.5. The findings indicated that the failure mode of the CFST composite column transitioned from oblique compression shear failure to localized shear failure in the joint areas as shear-span ratio decreased. An extended analysis of the parameters was carried out utilizing the ABAQUS finite element model. The analysis indicates that the ultimate shear resistance capability of steel-concrete composite columns increases with the rise in the strength of the batten concrete, the batten concrete thickness-to-span ratio, and the outer diameter of column limbs. However, it decreases with an increase in shear-span ratio. The accuracy of the calculation methods for existing similar structures was assessed, and based on the force transmission mechanism of CFST composite columns, theoretical and simplified calculation methods were proposed that meet engineering precision requirements. Consequently, this method offers a valuable theoretical reference for engineering applications.
